摘要
依托3座市政污水处理厂开展了混凝沉淀-深床滤池-消毒深度处理工艺的效果分析。生物二级处理出水中需要关注SCOD、NO_(3)^(-)-N、颗粒性磷和PO_(4)^(3-)-P的去除效果,这些组分占COD、TN和TP的平均比例分别为71%、87%和75%以上。深度处理对COD、TN和TP的平均去除率分别为25.4%、15.5%和47.6%,ΔCOD/ΔPAC与ΔTP/ΔPAC(平均质量比)分别为1.4和0.07。深度处理显著提升了出厂水水质,对COD、TN、TP、SS和色度稳定达标起到了保障作用。
Effects of coagulation/sedimention-deep bed filter-disinfection were introduced in this paper,which carried out on the three municipal wastewater treatment plants.SCOD,NO_(3)^(-)-N,particulate phosphorus-P and PO_(4)^(3-)-P are the main portion in the effluent of the secondary clarifier,and the corresponding average value was more than 71%、87%和75%.The average removal rates of COD、TN and TP in advanced treatment were 25.4%,15.5%and 47.6%respectively.ΔCOD/ΔPAC andΔTP/ΔPAC(the average mass ratio)was 1.4and 0.07.The effluent quality was significantly improved after the advanced treatment stage,and this stage guarantees the stability of COD,TN,TP,SS and chromaticity.
